U.S. scientists working on aging mice were able to boost the development of muscle stem cells in older tissues by using RNA interference to inhibit the pathway of TGF-beta, a molecule that prevents muscle growth. The findings may pave the way for new treatments for diseases tied to aging, such as Alzheimer's and Parkinson's, the researchers said.

Researchers at the Technical University of Munich found that PET/CT detected breast cancer recurrence in 67% of patients and affected treatment strategies in about a third of the cases. "We believe PET/CT has prognostic potential for restaging breast cancer," said the researcher who presented the study at the SNM meeting this week.

A prototype of a semiconductor-based PET brain scanner was more effective at spotting partial epilepsy and nasopharyngeal cancer than the conventional version, a Japanese study found. Researchers believe the technology could help detect cardiovascular disease, neurological disorders and cancers in their early stages.
